* Register - Data is read from (or written to) a register.
* Absolute - An exact memory address is specified.
* Immediate - An [[Immediate Value|immediate value]] is used used as an argument.
* Indirect - A memory address is specified, which contains the address of the memory for reading/writing. Effectively, the argument in this addressing mode is the address of a pointer to the actual data.
* Base plus offset - An absolute or indirect memory address is specified as a base address along with a register (or immediate value) that contains an offset value. The base and offset values are added together, and the resulting address is used to read/write data. In some cases, the computed address may be written back to a register, so that as you iterate through a loop, successive data locations are accessed.
